The purpose of our usual driving is to get to where we want to go faster, but this process is a bit boring. If there are some adjustments, it will be more enjoyable. With the accompanying music, the usual long road will not feel so long. Now, the car audio system is very important. A lot of friends can't understand the various kinds of audio input interfaces on the new models. They don't know what skills they use when they are normally used. Today, we will mainly talk about the use of various audio source interfaces and precautions for using them in peacetime.
Various interfaces introduced:
At present, the audio players on mainstream models are very rich in audio input. They mainly include radios, optical discs, USB interface inputs, AUX terminal inputs, SD cards and Bluetooth transmissions, and car hard drives. Some models are equipped with special features. Input interface, such as Apple's Dock interface, to synchronize the data in the Apple device.
1. Radio radios can be found in almost all cars, and are most often used by most drivers. In cities, the frequency of having rich music and the frequency of traffic broadcasting timely road conditions are very popular. In some places, there are more than one good radio station, and the callback frequency is very troublesome. Actually, there is a function on the radio to save your favorite radio station. After the six buttons on the radio are pressed, you can store the current station. You can hear which station you press. On the line, when there are 6 keys, you press the “FM†button more, and you can store 6 stations in FM2 and FM3 respectively, so that the number of stored stations reaches 18 as many.
The current mainstream car radio has two frequency bands, namely AM and FM. FM is a microwave transmission with high signal quality, but it has a small coverage and is greatly affected by geographical factors. It is mostly used for city broadcasting. For example, local city radio stations can listen to FM. AM is medium-wave transmission with stable signal quality and wide coverage. However, it is affected by weather conditions and is generally preferred as long-distance transmission, such as China Radio International and China National Radio.
In order to get a good radio signal, the antenna of the vehicle is a very important factor besides the reason that the radio is launched. There are mainly several types of antennas on the models running on the street. The first one is a shark fin antenna. And the new Korean models like to use; the second is an external fixed antenna, also divided into manual and automatic expansion, there is a more used is a printed antenna, in the rear windshield glass and electric heating wire is not connected to the line Is printed antenna.
2, CD This in addition to some commercial models, the CD-ROM drive should also be the basic configuration, the CD-ROM drive is divided into two kinds of CD and DVD, CD only contains audio, and DVD is audio and video can be stored. In many audio input methods, CD is the best sound quality, but the capacity is less, usually a CD capacity of more than a dozen songs, even if burned according to the MP3 format does not exceed 100 CDs, and genuine CD's The price is relatively high, so after the emergence of USB and AUX interfaces, the use frequency is gradually decreasing.
3, USB interface (SD card slot)
The emergence of the USB interface has changed people's usage habits for decades, greater capacity, can be updated at any time the track and compact and lightweight and other features, making it the current mainstream audio input, car manufacturers are basically in the new The model is equipped with a USB interface.
The use of the SD card slot is similar to that of the USB port, but the limitation is relatively large. Only the SD card can be used. The microSD card and the miniSD card cannot be used, and the SD card must be passed through the card reader when downloading data. Device transmission. USB interface and SD card slot input on most models mainly support audio files in MP3 and WMA formats, but there are few supported devices for lossless audio files such as APE or FLAC.
4, AUX terminal AUX terminal refers to 3.5mm standard double head interface, can make any audio device with a headphone jack connected to car audio, including MP3, mobile phones, tablet computers and so on. Only need a 3.5mm interface cable to receive music from these devices, and from the car speakers, the sound quality is acceptable.
5. Bluetooth transmission This is a relatively advanced audio input method in the current car. Using Bluetooth devices such as mobile phones or tablet PCs in the car can not only play music and video through Bluetooth, but also make calls and data synchronization. The convenience is very good.
6, car hard disk car hard drive currently only appears in some higher-priced models above, most of them are integrated with the car's multimedia system, its principle and U disk or SD card are similar, are storage devices, the system passed Previously copied audio and video data in the car hard disk to play, the advantage is the capacity is large, generally more than 30GB, can hold thousands of songs or hundreds of movies.
